OP

Quoted from StevenP:

OK. (Was posting from phone earlier so long messages are a PITA!)
The inserts don't illuminate the pf at all. (Insert light comes up from below, not down onto the pf.) What they do is direct fairly intense light right into your eyes when you look at the pf during play. That shrinks your pupils, so that everything else looks dark. Which is why the WOZ pf looks pretty dark, esp. between the flippers, even in a slightly lit room. As an example, shine a bright flashlight momentarily into your eyes; everything else will look dark for a while. When playing WOZ, the inserts keep your pupils small, so the barely-lit pf looks really dark by comparison.
As another comparison, look at the intensity of WOZ inserts compared to a regular pin with incandescent inserts. GI aside, that light will make everything else look darker and *not* illuminate the pf at all. In fact, it has the opposite effect. This is why I don't like many pins retrofitted with LEDs; they make it harder to see and follow the ball because of this effect, and sometimes cause the flicker/strobing that I find annoying.
Now, dimming the insert LEDs to a reasonable level (less bright, less saturated) will result in your pupils being more dilated, so the rest of the pf WILL be more visible and won't look so dark, even with a moderate amount of GI. Which is why I will repeat this request:
PLEASE UPDATE THE WOZ SOFTWARE TO ALLOW **SIGNIFICANT** DIMMING OF THE INSERT LEDS!!!! IT WILL MAKE THE PLAYFIELD EASIER TO SEE AND MORE PLAYABLE!!!!!!!!!!!
